Vasovagal sensations (e.g., dizziness, nausea, and fainting) are one of the main reasons people find blood donation unpleasant. A better understanding of predictors of vasovagal sensations during blood donation could inform interventions designed to increase donor return rates. The present investigation examined the extent to which experience with blood donation and vasovagal sensations during blood donation uniquely predict the likelihood of donor return, even when controlling for affective expectancies. Participants presenting at community blood drives indicated how many times they have given blood and provided ratings of expected anxiety, pain, disgust, as well as fear of fainting before giving blood. After donating, participants completed a measure of vasovagal sensations experienced during blood donation. They also rated the pleasantness of the experience and willingness to donate blood in the future. The findings showed that experience with blood donation and vasovagal sensations during blood donation uniquely predicted willingness to donate blood in the future even when controlling for age and negative affective expectancies about giving blood. This finding suggests that vasovagal sensations and experience with blood donation have unique (and perhaps additive) effects on willingness to donate blood in the future, suggesting that behavior modification interventions that directly target these variables could potentially increase donor retention.
